Description

Technical Field

[0001] This application relates to the field of workpiece processing technology, and in particular to a caliper inspection device. Background Technology

[0002] The current production line lacks the capability to test caliper slip force, resulting in low efficiency in the caliper slip force testing process. Furthermore, the existing caliper marking process relies on manual operation, which not only increases labor costs but also leads to significant fluctuations in marking quality (such as position and clarity) due to human factors, making it difficult to meet customer requirements for consistency and efficiency. Utility Model Content

[0003] This application provides a caliper testing device. The caliper includes a body and a brake pad, with the brake pad and body slidably connected. The testing device includes: a turntable on which the caliper can be mounted, and the turntable can rotate to sequentially switch the caliper between at least a first station, a second station, and a third station; a slip force testing device for testing the slip force of the caliper located at the second station, wherein the slip force is the frictional force generated during the sliding of the brake pad relative to the body; and a marking device for marking the caliper located at the third station.

[0004] According to an embodiment of this application, by integrating the slip force testing device and the marking device into multiple stations on a turntable, the rotation of the turntable drives the caliper to switch between multiple testing stations, thereby realizing the testing of the caliper through an assembly line, which improves the efficiency and automation of caliper testing.

[0005] In some embodiments, the turntable includes a clamp, which includes: a first clamping portion and a second clamping portion disposed opposite to and spaced apart along a first direction, with a first portion of a caliper between the first clamping portion and the second clamping portion, the first direction being perpendicular to the rotation axis of the turntable; an elastic member extending along the first direction, the elastic member being disposed on the side of the first clamping portion opposite to the second clamping portion, one end of the elastic member being connected to the first clamping portion along the first direction; a first push plate located on the side of the elastic member opposite to the first clamping portion; and a first driving portion for driving the first push plate to move toward the elastic member along the first direction to compress the elastic member, thereby causing the first clamping portion to press the first portion onto the second clamping portion.

[0006] According to the embodiments of this application, the turntable can compress the elastic element through the drive unit to press the first part of the caliper onto the clamping part of the fixture, thereby completing the fixation of the caliper by the turntable. By adopting the above technical solution, the compression characteristics of the elastic element allow the clamping force to be dynamically adjusted with the drive unit, avoiding the risk of overpressure caused by rigid clamping.

[0007] When there is a slight deviation in the size of the first part, the elastic deformation can compensate for the deviation, ensuring stable clamping without damaging the workpiece.

[0008] In some embodiments, the turntable further includes a collection device for collecting debris generated by the calipers during the coding process.

[0009] According to embodiments of this application, a collection device is used to collect metal debris, dust, or chemical fumes that may be generated during the coding (such as laser marking) process, so as to avoid sensor misreading, performance degradation of sensitive elements, or shortened lifespan caused by these materials drifting to other detection equipment.

[0010] In some embodiments, the brake pads include: an inner brake pad and an outer brake pad, which are spaced apart along a second direction perpendicular to the rotation axis of the turntable. The slip force testing device includes: a second push plate, spaced between the inner and outer brake pads; a second drive unit connected to the second push plate, used to drive the second push plate to move along the second direction, thereby causing the second push plate to push the inner or outer brake pad to slide relative to the main body; and a force sensor located between the second drive unit and the second push plate, used to measure the thrust exerted by the second drive unit on the inner or outer brake pad, the thrust being used to characterize the slip force.

[0011] According to an embodiment of this application, the slip force testing device extends a second push plate between the inner brake pad and the outer brake pad. The driving force of the second drive unit drives the inner brake pad and the outer brake pad to move together with the second push plate in a driven manner. During this process, a slip force is generated between the inner brake pad and the outer brake pad and the caliper body. The movement of the inner brake pad and the outer brake pad against the slip force relies on the pushing force of the second drive unit on the push plate. Therefore, this pushing force can be used to characterize the slip force.

[0012] The technical solution adopted in this application integrates the force sensor into the force application path, which can detect the actual thrust of the drive unit in real time and accurately, reducing the error caused by friction or inertia of the transmission mechanism. Characterizing the sliding force of the inner and outer brake pads with thrust can simplify the test structure. That is, only one force sensor is needed to complete the sliding force test of the brake pads on both sides, thus improving the test efficiency.

[0013] In some embodiments, the slip force testing device further includes: a third push plate, which is spaced between the inner brake pad and the outer brake pad; and a third drive unit, which is connected to the third push plate and is used to drive the third push plate to move along a second direction so as to push the inner brake pad and the outer brake pad to a preset position, which is the initial position of the inner brake pad and the outer brake pad relative to the caliper body during the slip force test.

[0014] In some embodiments, the second pusher plate includes a cutout portion, and the third pusher plate can be embedded in the cutout portion.

[0015] According to an embodiment of this application, the third push plate is embedded in the hollow part of the second push plate and can be freely pushed out to advance the second push plate. Before each sliding force test begins, the third push plate pushes the inner and outer brake pads to a preset position through the third drive unit. The advantage of the technical solution adopted in this application is that the operation of pushing the inner and outer brake pads to the preset position can ensure that the initial conditions of each sliding force test are the same, and avoid the interference of the different initial positions of the inner and outer brake pads on the experimental results.

[0016] In some embodiments, the coding device includes: a fourth driving unit for driving the coding device to move along a third direction, the third direction being perpendicular to the rotation axis of the turntable; and a fifth driving unit for driving the coding device to move along a fourth direction, the fourth direction being perpendicular to the third direction and perpendicular to the rotation axis of the turntable.

[0017] In some embodiments, the detection device further includes: a first slide rail extending in a third direction, a fourth driving unit capable of driving the coding device to slide along the first slide rail; a second slide rail extending in a fourth direction, a fifth driving unit capable of driving the coding device to slide along the second slide rail.

[0018] According to an embodiment of this application, the coding device achieves precise movement control through the cooperation of multiple drive units and mutually orthogonal slide rails.

[0019] In some embodiments, the caliper testing device further includes a base for adjusting the height of the caliper testing device along a fifth direction, which is parallel to the rotation axis of the turntable.

[0020] According to the embodiments of this application, the base can flexibly adjust the height of the caliper testing equipment, enabling the caliper testing equipment to better perform sliding force tests on different calipers, thereby improving the flexibility of the sliding force testing process.

[0021] In some embodiments, the turntable drives the caliper to switch sequentially between at least the first station, the second station, the third station, and the fourth station.

[0022] According to an embodiment of this application, the fourth station can be used as a reserved expansion station to test other performance characteristics of the caliper, thereby improving the scalability of the caliper testing equipment. Attached Figure Description

[0045] This application provides a caliper testing device. The method provided in this application can improve the testing and marking efficiency of calipers.

[0046] To clearly describe the technical features of this application, specific embodiments and accompanying drawings are provided below for detailed explanation. Furthermore, reference numerals and / or letters may be repeated in different examples. This repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed. It should be noted that the components illustrated in the drawings are not necessarily drawn to scale. Descriptions of well-known components, processing techniques, and processes are omitted in this application to avoid unnecessarily limiting the scope of the application.

[0047] It should be noted that, in the embodiments of this application, the X, Y, and Z directions can be perpendicular to each other. In some embodiments, the Z direction can be a vertical direction.

[0048] Figure 1 An exemplary structure of the caliper 40 in an embodiment of this application is shown. (Reference) Figure 1 The caliper 40 includes a body 41 and a brake pad 42. The body 41 may be made of materials such as cast iron, aluminum alloy, or carbon fiber polymer. The brake pad 42 can be slidably connected to the body 41.

[0049] Brake pad 42 may include inner brake pad 421 and outer brake pad 422. The material of brake pad 42 may be metal fiber or ceramic material, etc., which is not limited in this application. Caliper 40 may be installed on the vehicle. During the braking process of the vehicle, the drive system of caliper 40 (e.g., hydraulic drive system) can push the inner brake pad 421 and / or outer brake pad 422 to slide relative to the main body 41, so that the inner brake pad 421 and outer brake pad 422 clamp the brake disc of the vehicle tire to achieve the braking effect.

[0050] During the sliding process of the brake pad 42 relative to the main body 41, the brake pad 42 will experience resistance from the main body 41, such as sliding friction between the brake pad 42 and the main body 41. In this embodiment, this resistance experienced by the brake pad 42 is referred to as the "slip force" of the caliper 40. It is understood that the existence of the slip force will affect the response speed and braking reliability during vehicle braking. Therefore, it is necessary to detect the slip force of the caliper 40 to control it within a reasonable range.

[0051] However, current caliper production lines lack slip force testing equipment, making it impossible to efficiently test the slip force of calipers.

[0052] In addition, to mark the calipers, it is necessary to mark them with pre-set markings for identification. Currently, the marking method for calipers is manual, which requires additional manpower and the marking effect is not good. In view of this, this application provides a caliper inspection device that integrates a slip force testing device and a marking device. The following description of this application is made with reference to the accompanying drawings and embodiments.

[0053] This application provides a caliper testing device comprising a multi-station turntable, a sliding force testing device, and a marking device. The caliper is mounted on the turntable, which can move the caliper between different stations. When the caliper is at one station, the sliding force testing device performs a sliding force test on the caliper at that station. When the caliper is at another station, the marking device marks the caliper at that station. It is understood that this application can achieve the flow of the caliper between the sliding force testing device and the marking device by switching stations, forming an assembly line and improving the automation level of the sliding force testing and marking processes.

[0054] Figure 2 A schematic diagram of the overall structure of the caliper testing device 00 provided in an embodiment of this application is shown. (Refer to...) Figure 2 The caliper testing equipment 00 includes a turntable 10, a sliding force testing device 20, a marking device 30, a base 60, and a collecting device 70. The turntable 10 is rotatably connected to the base 60, and the turntable can rotate relative to the base 60 about a rotation axis L1. As an example, the rotation axis L1 is parallel to the Z-axis. The caliper 40 can be mounted on the turntable. When the turntable rotates relative to the base 60, it can drive the caliper 40 to switch sequentially between the first station 01, the second station 02, the third station 03, and the fourth station 04, forming a production line. The collecting device 70 is mounted on the third station 03. When the caliper 40 switches to the third station 03, the collecting device 70 can store the caliper 40 inside.

[0055] For example, the first station 01 is set in the negative direction of the Y-axis, the second station 02 is set in the negative direction of the X-axis, the third station 03 is set in the positive direction of the Y-axis, and the fourth station 04 is set in the positive direction of the X-axis.

[0056] A sliding force testing device 20 is installed at the second station 02 to test the sliding force of the caliper 40 when it is switched to the second station 02. A marking device 30 is installed at the third station 03 to mark the caliper 40 when it is switched to the third station 03. The marking method of the marking device 30 may include laser marking, engraving marking, spraying, or sticker marking, which is not limited herein. Taking laser marking as an example, when the caliper 40 is rotated to the third station 03 by the turntable 10, the marking device 30 marks a preset mark on the target area of ​​the caliper 40 through high-temperature ablation, oxidation discoloration, or engraving.

[0057] The caliper inspection equipment 00 provided in this application integrates the sliding force testing device 20 and the marking device 30 onto a multi-station turntable 10. By switching stations, the caliper 40 can move between the sliding force testing device 20 and the marking device 30, forming an assembly line. This improves the automation level of the sliding force testing and marking processes, increases the efficiency of sliding force testing and marking, and enhances marking quality and stability. In one embodiment provided in this application, the fourth station 04 can be a reserved expandable station. The fourth station 04 can reduce the time required for production line modification when the process changes. For example, when a process for detecting the thickness of brake pads 42 needs to be added, the turntable 10 can simply add a laser thickness gauge and set it at the fourth station 04 without refactoring other devices. The reserved fourth station 04 as an expandable station enhances the versatility of the caliper inspection equipment 00.

[0058] In one embodiment provided in this application, reference is made to... Figure 2 The caliper 40 is set inside the collecting device 70 to perform the coding operation. During the coding process, the debris generated by the laser is blocked by the collecting device 70 to avoid affecting other devices. The collecting device 70 can also collect the debris and remove it from the coding work area to keep the caliper 40 clean.

[0059] The collection device 70 provided in this embodiment can reduce the impact of debris generated during the coding process, keep the caliper detection equipment 00 at a high level of cleanliness, and prevent debris from contaminating the surface of the caliper 40. In addition, it can also prevent conductive debris from entering the bearing of the turntable 10 and extend the life of the turntable 10.

[0060] In one embodiment provided in this application, reference is made to... Figure 2 The sliding force testing device 20 is slidably connected to the base 60 along the Z-axis. As an example, the fifth direction is parallel to the Z-axis. The sliding force testing device 20 can slide on the base 60 along the Z-axis direction, adjusting the height of the sliding force testing device. The sliding force testing device 20 mounted on the base 60 can perform sliding force tests on calipers 40 of different sizes and heights by adjusting its height, improving the flexibility of the testing process.

[0061] Figure 3 A schematic diagram of the fixture 11 provided in an embodiment of this application is shown. It should be noted that... Figure 3 In this example, the reference direction of fixture 11 is defined with the caliper 40 rotating to the second station 02 as an example. It can be understood that when the caliper 40 rotates to other stations, the reference direction of the fixture can change accordingly.

[0062] refer to Figure 3The clamp 11 includes a first clamping part 111, a second clamping part 112, an elastic member 113, a first push plate 114, and a first driving part 115. As an example, the second direction is parallel to the Y-axis. The first clamping part 111 and the second clamping part 112 are arranged opposite to each other and spaced apart along the Y-axis. The elastic member 113 is located on the side of the first clamping part 111 facing away from the second clamping part 112. One end of the elastic member 113 along the Y-axis is connected to the first clamping part 111, and the other end is connected to the first push plate 114 along the Y-axis.

[0063] The first clamping part 111 and the second clamping part 112 are used to accommodate the first part 411 of the caliper body 40. The first part 411 of the caliper body 40 can be understood as the clamped part of the caliper 40. The first clamping part 111 and the second clamping part 112 cooperate to fix the first part 411 of the caliper 40. When the first part 411 is not clamped, there is a space between the first clamping part 111 and the second clamping part 112 for inserting and removing the first part 411. When the first driving part 115 drives the first push plate 114 to move towards the first clamping part 111 along the Y-axis direction, it can compress the elastic member 113 to deform and generate elastic potential energy. The elastic member 113 transmits the thrust to the first clamping part 111 through the elastic potential energy, pushing it closer to the second clamping part 112, so that the first part 411 is pressed onto the second clamping part 112.

[0064] In some embodiments of this application, the first clamping part 111 and / or the second clamping part 112 may include symmetrical or asymmetrical mechanical claws or grippers. The elastic element 113 may include a spring or a hydraulic device. The first drive part 115 may include a cylinder, a servo motor, or a linear module. This application does not limit the options in the above embodiments.

[0065] The clamp 11 provided in this embodiment effectively utilizes the radial space of the turntable 10 by arranging the first clamping part 111, the first portion 411, the second clamping part 112, the elastic element 113, the first push plate 114, and the first driving part 115 in a linear series arrangement along the Y-axis. The driving force of the first driving part 115 acts on the first push plate 114, indirectly pushing the first clamping part 111 by pushing the elastic element 113, thus preventing surface damage or deformation of the caliper 40 caused by rigid clamping. Furthermore, the elastic element 113 in this embodiment can also adjust the clamping force according to the actual size of the first portion 411, preventing problems such as the caliper 40 not clamping securely due to manufacturing tolerances of the parts.

[0066] Figure 4 An exemplary structure of the slip force testing device 20 is shown. Figure 4The sliding force testing device 20 shown includes a second push plate 21, a second drive unit 22, a force sensor 23, a third push plate 24, and a third drive unit 25. As an example, the third drive unit is parallel to the X-axis. The second push plate 21 is spaced between the inner brake pad 421 and the outer brake pad 422 along the X-axis. The second drive unit 22 is connected to the second push plate 21 along the X-axis. The force sensor 23 is located between the second drive unit 22 and the second push plate 21. Exemplarily, the force sensor 23 is located at the connection between the second drive unit 22 and the second push plate 21. The third drive unit 25 is connected to the third push plate 24.

[0067] Figure 5 An exemplary structure of the second pusher plate 21 and the third pusher plate 24 is shown. (See reference...) Figure 5 The second push plate 21 also includes a hollow portion 211. The third push plate 24 can match the shape of the hollow portion 211 and leave a gap, and the third push plate 24 can be embedded in the hollow portion 211. The third push plate 24 embedded in the hollow portion 211 can be arranged together with the second push plate 21 between the inner brake pad 421 and the outer brake pad 422.

[0068] In some embodiments of this application, the second push plate 21 may be flat or wedge-shaped, and the material may be a wear-resistant material, such as chrome-plated steel. The cutout 211 on the second push plate 21 may be square, circular, or irregular in shape. The second drive unit 22 may include a motor, cylinder, or electric motor. The third drive unit 25 may include a servo motor, cylinder, or linear motor. This application does not limit the options in the above embodiments.

[0069] To avoid the impact of the different initial positions of the inner brake pad 421 and outer brake pad 422 on the test results, the inner brake pad 421 and outer brake pad 422 need to be moved to a preset position before the slip force test begins. The preset position standardizes the initial positions of the inner brake pad 421 and outer brake pad 422, ensuring that the inner brake pad 421 and outer brake pad 422 have the same distance from the housing 413 before each slip force test. Therefore, the slip force test can be performed in two steps:

[0070] First, before the sliding force test begins, the third push plate 24 can be pushed out of the hollow part 211 on the second push plate 21 by the third drive unit 25. The third push plate 24 will push the inner brake pad 421 and the outer brake pad 422 to the preset position, and then the third push plate 24 will be retracted into the hollow part 211.

[0071] In the second step, the second drive unit 22 can drive the second push plate 21 to move. When the second push plate 21 touches the inner brake pad 421, the pushing force of the second push plate 21 will cause the inner brake pad 421 to slide in the latch 412 on the main body 41 of the caliper 40. The hydraulic system in the caliper 40 will react this pushing force on the outer brake pad 422, causing it to move in the opposite direction. The sliding of the main body 41 on the latch 412 needs to overcome friction, which is the sliding force that the caliper 40 needs to detect. Since this pushing force is the transmission force of the driving force of the second drive unit 22, the force sensor 23 can record the value of the driving force of the second drive unit 22 on the second push plate 21 during the sliding process, that is, the value of the sliding force.

[0072] The sliding force testing device 20 also converts the detection of the sliding force of the caliper 40 into the detection of the pushing force of the second drive unit 22 on the second push plate 21 by using a force sensor 23 disposed between the second push plate 21 and the second drive unit 22. This simplifies the testing process, reduces the interference of the device on the testing process, and improves the accuracy of the sliding force test.

[0073] In addition, the slip force testing device 20, through the nested structure of the second push plate 21 and the third push plate 24, sets the inner brake pad 421 and the outer brake pad 422 in preset positions before the slip force test begins, avoiding adverse effects on the test results due to the different initial states of the caliper 40. This structural design saves space and materials, realizes the reuse of the third push plate 24, and makes the overall structure of the slip force testing device 20 more compact.

[0074] Figure 6 A marking device 30 is shown mounted on a caliper inspection device 00. (Reference) Figure 6 The coding device 30 includes a fourth drive unit 31 and a fifth drive unit 32. As an example, the third direction is set to be parallel to the X-axis, and the fourth direction is set to be parallel to the Y-axis. The coding device 30 is mounted along the Z-axis on a first slide rail 51 on the caliper inspection device 00. The first slide rail 51 extends along the X-axis, and the fourth drive unit 31 on the coding device 30 can drive the coding device 30 to move along the X-axis direction on the first slide rail 51. The first slide rail 51 is mounted along the Z-axis on a second slide rail 52. The second slide rail extends along the Y-axis, and the fifth drive unit 32 on the coding device 30 can drive the coding device 30 to move along the Y-axis direction on the second slide rail 52.

[0075] In this embodiment, the fourth drive unit 31 and the fifth drive unit 32 can drive the coding device 30 to move arbitrarily on the first slide rail 51 and the second slide rail 52 in the X-axis and Y-axis directions. Through the cooperation of the fourth drive unit 31 and the fifth drive unit 32, the coding device 30 can move arbitrarily in the two-dimensional rectangular coordinate system composed of the X-axis and the Y-axis, and accurately locate the target coding area on the caliper 40, solving the blind spot problem of the traditional two-dimensional coding device 30.

[0076] This embodiment uses a combination of independent multi-drive units and orthogonal and independent multi-slide rails to enable the marking device 30 to move in any direction within the plane space formed by the X-axis and Y-axis, allowing for more flexible marking of the area to be marked by the caliper 40, thus improving the flexibility and accuracy of the marking process.
